Looking for a Zimbra expert to recover missing emails and harden the server

Job ID: 34702553

Budget: $40 – $100 AUD

Hello. We have a Zimbra mail server. There are two tasks we want to perform:
1. A user has managed to lose all emails prior to last week and they are no longer visible in the inbox. However if you search you can view the missing emails so they are not deleted. We do have a backup of the server if required.
2. General hardening tasks to make the server more secure.
